Antarctic Surface Slope and Elevation Measurements from Airborne Lidar

Antarctica is the geographic scope of this data set containing geolocated surface elevation measurements. The data were collected by the ICECAP project, funded by the NSF, Antarctic Climate and Ecosystems CRC, NERC, and NASA. It was last updated in December 2012.

Use Cases

• Analyzing surface slope variations across Antarctica using geolocated elevation points.
• Mapping ice sheet topography and identifying surface features from photon counting lidar returns.
• Calibrating satellite altimetry data with high-resolution airborne profiler measurements.
• Studying temporal changes in surface elevation by comparing with other data sets from different years.

Strengths

• Data collected by a major international collaborative project (ICECAP) involving NASA, NSF, and other agencies.
• Utilizes advanced sensor technology including Sigma Space Mapping Photon Counting Lidar and Riegl Laser Altimeter.

Limitations

• Data recency is limited, with the last update recorded in 2012.
• Specific sample size, row count, and geographic granularity are unknown from the provided description.
